They go after the propylene glycol by chewing through your radiator hoses. Kills 'em dead, not to mention it's a long way to the parts store. Propylene glycol is super sweet and is a main ingredient in Grape flavor soda- yummy!!

You are correct George. Ethylene glycol is often the ingredient of anti-freeze. Many newer anti-freezes use propylene glycol because it is not as toxic especially when diluted. Still bad for the critters though.

Perhaps you could spray something on the tires and underside of the car that would repel the quilly little fuckers. Ammonia? WD-40? I think the government of Canada should solve this problem. They owe it to us Americans! I don't know why...but they do!

First i thought they could walk right up the wood into the fender wells but i guess its been takin care of... but that has to scratch the shit out of your cars, i see one person used looks like foil tape.
